Listerine mouth wash is very good for keeping your mouth fresh and fighting bad breath. Usually bad breath happens because of bacteria and decaying food stuck in your mouth and in between teeth. Listerine mouth wash is very strong and effectively kills all bad bacteria in your mouth and keeps it fresh and smelling good and minty. I rinse my mouth three to four times daily.
I recently had suffered tonsilitis and itchy throat. With regular use, those problems were cured because of listerine. It comes in different flavors. I like the cool mint one. I would recommend using it regularly for good oral hygiene and preventing cavities.
